DIY Female DB25 to Female DB9 Null Modem Adapter

The adapter will have two functions:

• Convert to Amiga Male DB25 serial port to a Female DB9 serial port

• Wired up for Null Modem connections

You will need a Female DB25 connector and a Female DB9 connector.

You only need connect 3 wires:

• Signal Ground (GND)

• Transmit (TX)

• Receive (RX)

The Transmit and and Receive needs to be crossed over.
